Heat-Treatment of 409 Stainless Steel Tubing
Heat-Treatment of 409 Stainless Steel Tubing
Common heat treatment methods for 409 stainless steel tubing include:
- Annealing: Heat to 1,600 – 1,700°F (870 – 925°C) to improve toughness and workability, then cool slowly to relieve stress.
- Solution Annealing: Heat to 1,800 – 1,900°F (980 – 1,040°C) to dissolve alloying elements, then cool rapidly to enhance corrosion resistance and properties.
- Normalizing: Heat to 1,600 – 1,700°F (870 – 925°C) and cool in air to improve material uniformity and performance.
- Aging Treatment: Heat to 1,200 – 1,400°F (650 – 760°C) to increase strength and hardness.
